WElGHlNG-SCALE.

SPECIFICATION forming part of Letters Patent No. 319,687, dated June 9, 1885.

Appliration filed March 2., 1855.

To all whom, it may concern:

Be it known that I, JOHN H. SrEvENs, of Sandwich, in the county of Barnstable, State of Massachusetts, have invented a certain new and useful Improvement in Veighing- Scales, of which the followingis a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is aside elevation representing my improved scale in position for use; Fig. 2, a vertical longitudinal section of the hopper detached; Fig. 3, aside elevation of the standard mounted on the hopper of a coffee-mill, and Fig. 4 a front view of the hopper detached.

Like letters of reference indicate corresponding parts in the different figures 0f the drawings.

My invention relates to that class of weigh ingscales which are provided with a beam and hopper; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective and otherwise de sirable device of this character is produced than is now in ordinary use.

The nature and operation of the improve ment will be readily understood by all con versant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the standard; B, the beam, and C the hopper orvessel for holding the coffee or other article being weighed. The beam, which is of the ordinary construction, is pivoted at x in the standard A, and provided with a horizontally projecting bifurcated bracket, D, at its forward end. The hopper O is preferably cylindricalin form, and is arranged vertically between the arms 2' of the bracket D, being provided with an open flaring mouth, d, and at either side witha laterally-projecting stud, f, which has a downwardly-proj ecting arm, 2, said lastnan1ed arms passing loosely through holes (not shown)in the arms t, and thereby pivoting or suspending the hopper in such a manner as to enable it to swing (No model.)

I or oscillate on a line with the beam B, butnot at right angles thereto. The bottom at of the hopper is pivoted or journaled at one side of its center by means of the rod Z, which passes horizontally through the body of the hopper, and is provided at one of its ends with the cross head or bar 15, the bottom being'lirmlysccured to the rod, and the rod adapted to turn in its bearings in the sides of the hopper. A spring-catch, k, is attached to that side of the hopper which is nearest the beam B, said catch being adapted to hold the bottom on in position when closed. An adjustable stud, 0', projects horizontally from the standard A, the object of said stud being to prevent the hopper from swinging too far toward the beam B, when the spring 7c is pressed outwardly toward the standard A to open the bottom at and dump the contents of the hopper. The standard A has its lower end slotted, as shown at o, and is detachably inserted in a socket, N, attached to the counter M. A table, Q, is mounted on the upper end of a vertically-arranged rod, R, which passes loosely through the counter M, and has its lower end jointed to a treadle, L, pivoted in the standard T, the table being adapted to be raised and lowered, as desired, by means of the treadle and rod.

In the use of my improvement the bottom at is first closed and secured by the catch It, after which the coffee or other article to be weighed is placed in the hopper G and weighed. The bag or other receptacle into which the coffee is to be dumped is then placed on the tableQand raised or lowered, as the case may be, by means of the treadle L, to bring it into proper position with respect to the hopper, after which the spring-catch 7c is pressed in the direction of the standard A until it releases the bottom at and permits the contents of the hopper to be dumped into the bag in a manner which will be readily obvious without a more explicit description. The standard A is slotted as shown at c, to enable the scale to be attached readily to the hopper H of a coffee-n1ill, thereby enabling the coffee to be weighed and dumped directly into the mill for grinding. I do not, however, confine myself to the use of the slot for securing the standard to the hopper H, as any other suitable means may be employed.

The bar If is used for closing the bottom an after I pivoted on said extension, and provided with the contents of the hopper have been dumped. the hinged bottom m, and with a spring-catch,

Having thus explained my invention, what 7c, attached to its side for retaining said bottom 15 I claim isin closed position, and a stop, 1*, attached to 1.
